Aniston having a baby food diet

A baby food diet consisting of 14 portions of pureed food a day is how Jennifer Aniston hopes to embody the phrase you are what you eat.

The diet has helped her lose 3kg. Despite her enviable body, Aniston is said to be insecure about her looks and flew in another personal trainer, Mandy Ingber, to have on the set of Just Go With It to make sure she held her own beside Decker.

Sources on the set confirmed her paranoia, telling the Daily Mail Aniston feared she might look old and out of shape in comparison. Also she is worried about working with a younger model.
